Engine/Transmission (1998.5 - 2002) What does this mean?

[WMatlock]

Checked codes and P1693 & P0216 came up. What are these codes?

 

[B.G. Smith]

P1693: Diagnostic trouble code detected in ECM/PCM. P0216: Fuel injection pump timing failure, high fuel supply restriction, low fuel pressure or possible wrong or incorrectly installed pump keyway. bg

They mean that you should check your fuel pressure ASAP, find a dealer for warrenty work, or start shopping for a VP. Does your truck run okay? Any stumbling, hard starting, etc... It could be a false code, but if it is real and your VP finally dies, you will be stuck by the side of the road.



ps. Go to the Discussion Forums/User Control Panel and fill out your signature by listing your truck stats. You might also fill out your profile with your location.

i have the same codes, truck runs fine, fuel pressure is fine, no CEL or hard starts or anything out of the ordinary

I belive it may be your fuel cap. It may not be on correctly, it may be loose or it may not be the correct cap.

I had an intermittent stall when putting it in gear, and an ocassional stumble when shifting into OD, it also stumbled on startup. This was happening for about a year. When the 0216 code finally showed up, I replaced (recently) the VP "proactively" just in case.



Just curious, how long have you had the code?

 

[WMatlock]

No hard starting,no stumbling,truck runs fine. The codes just showed up. I did have a box plugged into it,but I unplugged it because it made the engine surge. I couldn't feel it surge,but I could hear it. Just got too annoying to listen to.

i dont know when it first showed up, but it has been a few thousand miles miles since i discovered it, just randomly decided to do the key trick to check codes one day and there it was, i did have a bad lift pump about 15000 or so ago that was replaced very quickly so i guess the low fuel pressure could have something to do with it.
